By the continual appulfe of frefh Sap, fome, both of the aery, and ofall the other parts thereof are tranfmitted into the Pith s where, finding more room,it will yet more kindly be digested. Efpecially having the advantage herein of fome degree of Warmth being herein remoter from the Soi/, and, as it were, Tunn'd up within the Wood, or the Mafé of furrounding Vefels.

And that there maybea better Tranfition of the sap thus tinGured, to the feveral Organical Parts 5 therefore, none of themare clofe fet and compact within themfelves, feverally: For fo, they would be inacceffible to the Sap, and their inward Portions, wanting a due fupply of Aliment, would be ftarved. But the Vefels, both of Aer and Sap, being every where divided into Braced Portions, and other Parenckymous Portions, filling up the {paces every where betwixt (c) P.t.c.3. them (c)3 there is therefore a free and copious communication of the §.13-&c4.

Whereby, none of them want that Celandine, Dogftones and all of that Kindred, 29. §. IN THIS Nourifhment, the Principles of the Sap are, as is pow the (e: faid, concentred and locked up one within another: (b) Whence it is, yeral Parts that the Organical Parts, being cleanfed of their Contents, have none of are Nou- i : ‘ } 4 i Matter, which is neceflary either for their Nutrition, or for the good Eftate of their Ccxtents, or for the due period of their Growth. 27. § Ror the better Tempering of the feveral paits of te Sep, : & 5 ferve the Diametral Portions of the Parenchymous Body whichrun fometimes direétly through the Barque, as in Lovage, Parfley, &c. is defcribed f P.t.0.3. and figur'd (4) Which being, all or moft of them, continued be (d) s twixt both the Succiferous and the Acr-Veffels, from the Circumference to And thus all the Parts have a fit Aliment provided for their Nourifhment % §.7,8. which afcend into the Truk.
